History
History
The rifle was developed in the early 1990s in TsKIB SOO of Tula designers VN Telesh and Yu.V.Lebedev. It is basically an AKS-74U re-chambered for 9×39mm, it was designed as alternative to the AKS-74U. The TsKIB COO of Tula made several hundred of OTs-12s, which were transferred to the Interior Ministry security forces. Despite the good evaluation, the Tula Arms Plant did not put the rifle into mass-production. They instead opted for a bullpup configuration known as OTs-14 Groza, which became its successor. In 2018, a replica of the Tiss was reported to be designed by Daniel Fisher of KNS Precision.
Design
Design
The main design changes from the AKS-74U are in the bolt, barrel, muzzle-brake, and magazine. Early versions were made with a long barrel. The 20-round box magazine was designed so that it would be compatible with standard current-issue ammo pouches, but a larger 25-round magazine was in early production until its cancellation. The subsonic round showed superior penetration of cover at short and medium ranges (200–300 m) when compared to the 5.45×39mm. Criticism was placed on the Tiss since a user cannot clean the gas outlet.
